Abstract
This paper investigates the empirical relationship between military spending and economic growth in a large panel of advanced and developing countries over the period 1984–2014, with a particular focus on whether the growth impact of military expenditures varies with the type and level of security threats. Although there is extensive literature on the military-growth nexus, there is still no consensus on the nature and magnitude of this relationship. Using an expansive dataset and controlling for country-specific effects and potential endogeneity, we revisit this issue and reach two firm conclusions. First, military spending has no statistically significant direct (positive) effect on growth. Second, the nature and level of security threats do not alter the relationship between military spending and growth. Overall, the empirical results documented in the study suggest that military spending is simply not important or large enough in most countries to have a meaningful impact on growth.

Notes
The time dimension of our dataset actually starts from 1970, but the empirical analysis is based on the period 1984-2014 because of the inclusion of institutional variables from 1984 onwards.
Acemoglu (2009) provides a detailed overview of the evolution of endogenous growth models.
The list of countries is provided in Appendix Table 2.
The estimations results are robust to the inclusion of these extreme values.
The difference GMM approach of Arellano and Bond (1991), which uses only the first difference equation, yields similar results but with reduced statistical significance for some variables.
The initial level of real per capita income and educational attainments are treated as predetermined variables, while the type of political regime is considered to be weakly exogenous and others are included in a vector of potentially endogenous variables.
